Xen-users, I have what I think is a bug in the serial console interaction of Xen and Ubuntu. Essentially, the serial console appears to work just fine until it is passed off to dom 0 from Xen. Then it stops communicating with dom0, but still communicates with Xen, if I use the control-A escape sequence. Google will not show me anything related to this. I have local RS-232 serial console working

Hello List, I'm ironing out details to upgrade a few systems to CentOS7. My servers have BMC with Serial over LAN support. In C5 and C6, I determined how to have BIOS/POST, kernel, and serial console access. I'm reading up on the method to accomplish the pieces with C7. Presently SoL output works, so I see BIOS/POST messages and the GRUB boot list. My changes to enable serial

Is there a way to get GRUB2 and the kernel to run a "serial" console under KVM? I'm running a Fedora 20 desktop, with libvirt-managed VMs. When I run a CentOS 6 VM, I can set both the boot loader and kernel up to use ttyS0 and get a console compatible with "virsh console". When I try the same with a CentOS 7 VM, it doesn't work. If I set it to ttyS0, I just

On Debian Squeeze (2.6.32-5) running Xen 4.0, I have created 2 Ubuntu Lucid Lynx (Ubuntu 10.04) vms. The vms, in a stress test, pass a large file between them via nfs file sharing. A previous entry in this forum helped to establish that some ethernet cards improve VM IO performance. However, our box installed with better intel nics is still rebooting under heavy VM IO loads. The kernel call

Good evening everyone, I am attempting to compile Xen 4.2.1 from source on Ubuntu 12.10 and cannot for the life of me figure out what I am doing wrong. This is the script I wrote that I am running on a brand new install from ubuntu-12.10-server-amd64.iso apt-get update apt-get -y upgrade apt-get -y dist-upgrade reboot (uname -r returns back 3.5.0-23-generic) apt-get install -y build-essential

Hello, I hope that I am posting the correct list with this question. I have been trying to get VGA passthrough working on my system for some time now without success. I do not have the system with me right now, so I will not be able to provide any logs or error messages right now. I will be able to to do so in a couple of hours. I have a VT-d enabled system (Motherboard and CPU) on which I wish

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=703586 Ideas how to move this forward? Debugging techniques? I''m guessing that it''s specific to my hardware, since I''m not seeing anyone else complaining. Anyone else succeed in doing this on an EliteBook?

Hi! I''m experimenting with Xen 4 on Squeeze. Squeeze uses grub2 by default, and the config format has changed. I can''t for the life of me figure out where to set options for the hypervisor and the Dom0 kernel on bootup. It seems the grub2 stanza for xen is being generated by /etc/grub.d/20_linux_xen and that seems to have some provisions for receiving arguments, but I

Hey, I thought there was supposed to be an ability for domU''s to be put into a hibernated state (E.g. current running tasks and memory) when dom0 is shutdown or rebooted. When I look in my /etc/default/xendomains file, I have the variable''s "XENDOMAINS_SAVE=/var/lib/xen/save" and "XENDOMAINS_RESTORE=true". However, when I reboot, I always have to restart my

Hi There, Having some trouble discovering how to shutdown domU's without saving them. I have some awful power from the grid causing the backup battery system to initiate shutdown's on dom0, which is the desired result, however domU's are saving (which I don't want) and this takes a very long time (for whatever reason). As they shutdown, console does this

Hi, folks, Well, I get back from vacation, and three CentOS 7 boxes didn't come up this morning (my manager and the other admin did the update & reboot). On these three - but *not* another one or two, and I don't think those others are Dells, they're supermicro's - the 327 kernel fell into the rdosshell, I guess. I finally got one the three up by going back to the 228.14

Hi, I want to write a puppet module for xen on Debian. This module will need to manage one line in the file /etc/default/grub, namely the line starting with "GRUB_CMDLINE_XEN=". Currently I want to leave the rest of the file untouched. Which would be the best way to do this? I see two options: a) Do some `sed` magic on the file in a `exec` call. Downside: puppet won''t notice

Dear All I am using Centos 7 with Xen 4.6 on a Dell Poweredge T430 When the machine boots, after the 'Scrubbing Free RAM' message, I get a screen filled with little white squares until the login prompt, so I cannot see what is happening as the machine boots. Also there is nothing on the screen when I reboot. My /etc/default/grub is GRUB_DISTRIBUTOR="$(sed 's, release

Hello, First of all, I'm really not an expert so please correct me if I'm saying anything wrong. I noticed a difference when using grub2 or syslinux in my linux virtual console (tty[1-5]) which uses VGA text mode (no graphical mode). To be sure that I'm using this mode, I did: $ dmesg | grep -i vga Console: colour VGA+ 80x25 In my understanding when using the VGA text mode,

Dear George, Thanks for the input and ideas. Unfortunately bootscrub=false dos not work, not does setting nothing for vga, still get the 'Little white squares'!
